TROLLEY-WHEEL AND GUARD THEREFOR.

SPECIFICATION forming part of Letters Patent No. 793,304, dated June 27, 1905.

Application filed December 1'7, 1904. Serial No. 237,205.

Be it known that I, FRIDOLIN KoENIe, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in '1rolley-lVheels and Guards Therefor and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, and to hgures of reference marked thereon, wluch l form a part of this specification.

The present invention has reference generally to trolley-wheels and guards for electric railroads: and the inventionrelates more particularly to that class of trolley-wheels and guards for electric railroads which derive their motive power from overhead feedwires or coinluctors.

The principal object of the present invention is to provide a trolley-wheel and guard therefor of a novel and simple construction, in which the parts of the combined wheel and guard have been reduced to a minimum, and which shall be of such construction that all possibility of the trolley-wheel becoming disengaged or forced from its operative rolling contact or relation with the feed-wire or conductor is entirely obviated. known fact that the oscillation and jolting of the car and any unevenness in the road-bed has the tendency to throw the trolley-wheel in a downward direction, resulting in a disengagement of the wheel from said feed-wire or conductor. Such disengagement of the trol- Icy-wheel from the overhead feed-wire in the manner just stated is not only very inconvenicnt, but is apt to cause damage to the cross-wires or supports of the feed-wire or conductor and also to the trolley-pole by causing the said trolley-pole to come in forcible contact with the said cross-wires or supports, especially when the car is running at a high rate of speed; and it is the main purpose of this invention to avoid these serious objections by the production of a simple spring It is a wellconstruction of trolley-wheel and guard emactuated and controlled guard which will permit the trolley-wheel to move or roll along the feed-wire in either direction without any damage to the cross-wires or feed-wire supports.

Further objects of the present invention, therefore, are to provide a trolley-wlwcl which may be readily and quickly adjusted in its operative relation with the feed-wire or conductor and one of such construction that although the trolley-wheel is guarded upon the feed-wire or conductor still there is no danger of its meelutnism injuring the crosswires or supports of the said feed-wire or conductor.

\Vith the various objects of the present invention in view the same consists in the novel construction of trolley-Wheel and guard therefor, to be hereinafter fully set forth; and, furthermore, this invention consists in the various arrangements and combinations of the parts, as well as in the details of the construction of the same, all of which will be clearly described in the following specification and then finally embodied in the clauses of the claim; which are appended to and which form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the novel bodying the principles of the present invention. Fig. 2 is a longitudinal vertical section of the same, taken on line 2 2 in said Fig. 1 looking in the direction of the arrow .13; and Fig. 3 is a detail cross-section taken horizontally on line 3 C3 in said Fig. 2 looking in the direction of the arrow y.

Similar characters of reference are employed in all of the said above described views to indicate corresponding parts.

lle'ferring now to the said drawings, the reference character 1 indicates a complete trolley-wheel and guard embodying the features of this invention, and the reference character 2 indicates a portion of an overhead feedwire. The said trolley-wheel and guard comprises a trolley-wheel carrier 3, which consists, essentially, of a main body 4, provided at its lower end with a receivingsocket 5, in which is suitably secured a trolley-pole 6, preferably by means of rivets or pins 7 or in any other suitable manner. The main body portion 4 of the said trolley-carrier 3 is provided at its upper portion with a yoke-shaped part formed with a pair of upwardly-projecting arms or bars 8 and with a pair of downwardly-projecting arms or bars 9, these said arms or bars preferably forming an integral part of the said main body portion 4 of the trolley-wheel carrier 3. The said pairs of arms 8 and 9 are arranged in their relation to the said main body portion 4 at any desired angle, but preferably at the angle illustrated in Fig. 1 of the drawings. Rotatively arranged between the said upwardly-projecting arms 8 and upon a suitable pin or axle 10 is a trolley-wheel 11, the said wheel riding against the feed-wire or conductor 2 in the usual and well-known manner. Pivotally arranged so as to oscillate upon the said pin or axle 10 and between the said arms 8 and the sides of the trolleywheel 11, substantially as shown, are a pair of guard-arms 12, secured together at their lower ends 13 by means of a connection, preferably in the form of a cross-bar 14. This bar 14 preferably forms an integral part of the said arms 12, as illustrated in Fig. 2 of the drawings. The said arms 12 also extend in an upward direction on either side of the said trolley-wheel 11 and for some distance above the outer circumferential marginal edge of the trolley-wheel 11., so as to embrace the said feed-wire on opposite sides, as clearly shown in Figs. 1 and 2 of the drawings. As will be clearly understood, if by reason of the downward fling of the trolleypolc caused by the oscillation and jolting of the car or other cause the trolley-wheel 11 leaves the feed-wire or conductor 2 the said arms 12 will prevent the trolley-wheel 1 1 from being thrown to one side, whereby it would be caused to miss the feed-wire or conductor when regaining its normal position, and the said arms 12 will surely guide the said trolleywhecl 11 back to its operative relation with the said feed-wire or conductor 2, as will be clearly understood. The downwardly-pro jecting arms 9 of the main body portion 4 of the said trolley-wheel carrier 3 are provided, respectively, with a spring-tension adjustment comprising a connection or cross-bar 15, suitably secured between the said arms 9, but which is preferably slidably arranged in bear ings or guides 16 of the said downwardlypro jecting arms 9, the said connection or crosshead 15being movably and adjustably connected to the lower end portions 17 of apair of right and left threaded adjusting-screws 18. The said adjusting-screws 18 are provided with suitably-formed nuts or knurled fingerpieces 19, and the upper end 20 of each right and left threaded adjusting-screw 18 passes through a nut 21 and into a receiving chamber or socket 22, formed upon the said downwardly-projecting arms 9. The lower ends 23 of the said downwardly-projecting arms 9 are preferably provided with concave or semicylindrical openings 24 to permit of the passage of the said right and left threaded adjusting-screws therein when assembling the various parts of the spring-tension adjustment or the removal of the same for the purpose of making repairs.

The operation of the above described spring-tension adjustment will be clearly understood from an inspection of said Figs. 2 and 3 of the drawings, and need, therefore, not be further described at this time.

Secured to the said cross-bar or connection 14 of the said arms 12 is the one end 25 of a coiled spring 26, the lower end 27 of said spring being secured to the cross-bar or connection 15. It will be readily understood that this spring 26 has a tendency to positively keep the arms 12 in their upright positions on opposite sides of the feed-wire 2, thus readily guarding the trolley-wheel 11 in its passage along the wire or conductor 2 against accidental displacement therefrom. Furthermore, the pivotal arrangement of the said arms 12 is such that they readily pass under the cross-wires or supports of the said feed-wire 2 without any danger of injury to the parts, owing to the yielding arrangement of the said guard-arms 12, and no matter in which direction the car may be moving, whether in a forward or a backward direction, the said guard-arms 12 assuming the positions in a manner clearly indicated in dotted outline in said Fig. 1 of the drawings and as will be readily understood from an inspection of the said figure. As soon as one of the said cross-wires or supports is passed the tension of the distended coiled spring 26 immediately returns the said guard-arms 12 to their initial and normally upright positions.

From the foregoing description and from an inspection of the figures of the drawings it will be seen that the present invention provides a very simple and very effectively-operating means for guarding a trolley-wheel upon the feed-wire or conductor against accidental displacement, and the construction of the same is of such a character that no injury to the cross-wires or supports for the feed-wire or conductor or to the parts of the trolley-guard is possible. Furthermore, it will be seen that from the construction of the arms 12 the additional feature is produced of providing a guide for readily and quickly replacing the trolley-wheel against the feed wire or conductor when for any reason it has become necessary to remove the trolleywheel from the wire.

I am aware that changes may be made in the details ot the construction ot the device without departing from the scope of the present invention. llence 1 do not limit my invention to the exact arrangements and combinations of the parts of the device as described in the foregoing specification and as illustrated in the accompanying drawings, nor do I confine myselt to the exact details of the c mstruction ot the various parts thereot.
